WebQuestion: QUESTION 21 Calculate the pH of 0.44 M HF ( Ka= 6.8 x 10-4). 12.24 0.36 1.76 0.0173 QUESTION 22 Which of the following will cause this reaction to shift toward products? N2 (g) + O2 (g) = 2 NO (g) increasing [NO] increasing [N2] increasing the container volume о decreasing the container volume WebQuestion 10 options: A) 6.8 M B) 5.0× 10–6 M C) 1.0 × 10–2 M D) 0.070 M E) 0.15 M AI Recommended Answer: To find the concentration of HF required to have the same pH as 0.070 M HCl, we need to solve the following equation: Ka = 7.2 × 10–4 Ka = 7.2 × 10–4 Hence, the concentration of HF required to have the same pH as 0.070 M HCl is 6 ...
SOLVED: What concentration of HF (Ka = 7.2 × 10–4) has the same pH …
WebVIDEO ANSWER:Hi everyone in this question they ask calculate the ph of 0.44 Mueller HF K 6.8 into tenders to minus four. Given concentration. Find 44 Molar Jeff then K. A. Well 6.8. Thank you too. 10-2 -4 than ph they are so H plus that is equal to squared off. Came to see so H plus that is equal to square it off. 6.8 into 10-2 -4 In 2.44. So that is equal to 6.8 In … WebThe pH of a 0.25 M aqueous solution of hyrofluoric acid, HF at 25oc is 2.03.what is the value ka for HF? a)2.0 x 10-9 b)1.1 x 10-9 c)6.0 x 10-5 d) 3.5 x 10-4 e)None of these Calculate the pH of a buffer that is 0.058 M HF and 0.058 M LiF. the backrooms the lost tape
SOLVED: Okay. Now let
WebpKa = -log Ka = - log (7.1 X 10^-4) = 3.15 .... (1) pH = pKa + log [conjugate base] / [acid] = 3.15 + log (0.75 / 0.55) = 3.15 + 0.13 = 3.28. Hence, pH of the buffer is 3.28. pH of the … WebTo calculate the pH of a solution with a concentration of 0.02 M methanoic acid, we need to know the concentration of methanoic acid, Ka, and the pH of a solution with that concentration. Ka = 1.6x 10-4M We can find the pH of a solution with 1.6x 10-4M of methanoic acid by using the pH scale. WebCalculate the pH of a 0.050 M solution of HF. (Ka = 3.5 x 10-4) Calculate the pH of a solution that is 2.00 M HF, 1.00 M NaOH, and 0.439 M NaF. (Ka = 7.2\times10-4) Explore our homework questions and answers library. Search. Browse.
